I apologize, but I'm not sure what you mean by "sw 165". This could be an abbreviation or code that isn't clear without more context. Could you please provide more information or clarify what you're asking about? Is it possibly related to:

1. A software version number?

2. A section in a document or book?

3. A specific model or product code?

4. Something else entirely?

If you can give me more details about what you're looking for, I'll be better able to assist you with your query.
